While Neram is near-perfect, no article is fair without critique. Some viewers find the first 20 minutes slightly slow as the film establishes the "worst day ever" trope. Also, the logic of the time reset is never fully explained—a deliberate choice by Puthren, but one that might bother hardcore sci-fi fans looking for rules. However, in a film that prioritizes style and emotion over physics, this is a minor nitpick.
Neram was made on a relatively low budget, but the production quality was high-class.
The soundtrack for Neram was composed by D. Imman, who is known for his work on several Tamil films. The music is a mix of energetic and romantic tracks that complement the film's tone.
